"This is the first time I've been about to experience Pandora in a tactile way," Landau said Friday, surprising a group of journalists and bloggers who had come to get a look at the new park. Landau produced both Titanic and Avatar with director James Cameron.

At the attraction, guests will be able to walk beneath Pandora's floating mountains, see exotic glowing plants and animals and take a ride on the back of a flying banshee in the Valley of Mo'ara. The glowing land of the blue Na'vi people has been under construction since 2014 and cost of $500 million, theme park experts estimate.
